2. What is Systems Engineering An Approach A Discipline Brief History- Bell Labs, Apollo project The Systems Engineering Process System Life Cycle-A Detailed Approach Conceptual Stage, Technical Feasibility Stage, Development Stage, Commercial Validation & Production Preparation Stage, Full Scale Production Stage, Product Support Stage, Disposal Stage O.T. Okpechi

3. Technical Feasibility Stage Subsystem Identification Trade-off Studies System Integration and Interface Definition Preliminary breadboard- Level Testing System design requirements and development of preliminary plans Preperation of a proposal for the development stage. LIFE- CYCLE COST ESTIMATIONS MUSTS MUST NOTS WANTS DON’T WANT Fadi Bader *Conceptual stage spends about 1% of the cost of project, the decisions made therein determine about 70% of life-cycle cost of the product. *In the Technical Feasibility Stage, about 7% of the development costs has been spent, but about 85% of life cycle costs are determined.

4. Design, Testing and Development are done concurrently on prototypes to make improvements. Development is not limited to just physical activities. -Quality Assurance, Coordination, Planning, Management, Improvement and Morale and Satisfaction Jas Sehmbey

5. Planning for Production – Supply Chain Management Availability of Resources Relationships with Suppliers / Distributors – Production Planning Facility Design – Upgrade Existing – New Facilities Production – Build Facilities “Shake Down” – Produce and Distribute – Remain Flexible to Changes Six Sigma, etc… Christopher Norman

6. Preparation of technical manuals Preparation of O/M manuals Customer service program Development of warranty plans Manufacture and distribution of repair parts and replacements Being close to the customer may lead to : In the early stages of product or design process Example: FGD (Flue-Gas Desulfurization) to remove waste (SO2) from exhaust Improvement in subsequent production New product spin-offs Major product design changes Abdulrahman Alansari
